About Bonterra Resources Inc.

Bonterra is a Canadian gold exploration company with a portfolio of advanced exploration assets anchored by a central milling facility in Quebec, Canada. The company's assets include the Gladiator, Barry, Moroy and Bachelor gold deposits, which collectively hold 1.24 million ounces in measured and indicated categories and 1.78 million ounces in the inferred category.

In November, 2023, the company entered into a earn-in and joint venture agreement with Osisko Mining Inc. for the Urban-Barry properties (the JV agreement), which include the Gladiator and Barry deposits. In October, 2024, Gold Fields Ltd. completed the acquisition of Osisko Mining for $2.16-billion. Gold Fields is now the counterparty to the JV agreement and can continue to earn a 70-per-cent interest in the joint venture by incurring $30-million in work expenditures until November, 2026 (including expenditures incurred by Osisko Mining prior to October, 2024). This strategic transaction highlights Bonterra's dedication to advancing its exploration assets, marking a significant step toward development.
